ACR User Dialogs not working in Android PCL

I am trying to use ACR User Dialog in my PCL Project. It works like a charm in my iOS project build but when I try to build my Android Project, it gives me the below error:

Exception while loading assemblies: System.IO.FileNotFoundException: Could not load assembly 'AndHUD, Version=1.2.0.0, Culture=neutral, PublicKeyToken='. Perhaps it doesn't exist in the Mono for Android profile?
File name: 'AndHUD.dll'
at Java.Interop.Tools.Cecil.DirectoryAssemblyResolver.Resolve(AssemblyNameReference reference, ReaderParameters parameters)
at Java.Interop.Tools.Cecil.DirectoryAssemblyResolver.Resolve(AssemblyNameReference reference)
at Xamarin.Android.Tasks.ResolveAssemblies.AddAssemblyReferences(DirectoryAssemblyResolver resolver, ICollection`1 assemblies, AssemblyDefinition assembly, Boolean topLevel)
at Xamarin.Android.Tasks.ResolveAssemblies.Execute(DirectoryAssemblyResolver resolver) TimPapp.Droid

I already have AndHUD 1.2.0 package installed in NuGet. Any idea what can be the reason? Appreciate any help.
